摘　　要：本文主要叙述了SP-1多功能外加剂的性能特点和应用概况。该剂是结合国情,采用合成和复合相结合的工艺研制而成的一种可溶性粉状物,其主要特点是掺入混凝土中后能显著地减少坍落度的损失,并具有增大混凝土坍落度、增加强度、节约水泥、改善和易性等优点,能满足商品混凝土、流化混凝土和泵送混凝土的需要。The property features and the applications of SP-1 multipurpose admixture are described in this paper. This admixture is a soluble powder developed by a process of combining the synthetic method with the com- posite method according to the national conditions of China, whose main features are capable of reducing slump loss, increasing slump and strength, saving cement and improving workability of the concrete after it is added to concrete. The admixture can meet the needs of commercial, fluidized and pumping concretes.
